PLAXIS 3D is a finite element package intended for three-dimensional analysis of deformation and stability in geotechnical engineering. It is equipped with features to deal with various aspects of complex geotechnical structures and construction processes using robust and theoretically sound computational procedures.

With PLAXIS 3D, complex geometry of soil and structures can be defined in two different modes. These modes are specifically defined for Soil or Structural modelling. Independent solid models can automatically be intersected and meshed.
